2-cases.js

// A set of words can be grouped together in different cases.

// For example, "hello there" in snake case would be written "hello_there"
// UPPER_SNAKE_CASE means taking a string and writing it in all caps with underscores instead of spaces.

// Implement a function that:

// Given a string input like "hello there"
// When we call this function with the input string
// it returns the string in UPPER_SNAKE_CASE, so "HELLO_THERE"

// Another example: "lord of the rings" should be "LORD_OF_THE_RINGS"

// You will need to come up with an appropriate name for the function
// Use the MDN string documentation to help you find a solution
// This might help https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/toUpperCase

function toUpperSnakeCase(str) {
    // Step 1: Replace all spaces with _
    const withUnderscores = str.replace(/ /g, '_');
   
    // Step 2: Convert to uppercase
    const upperCase = withUnderscores.toUpperCase();
   
    return upperCase;
}

// Test 
console.log(toUpperSnakeCase("hello there"));           // "HELLO_THERE"
console.log(toUpperSnakeCase("lord of the rings"));     // "LORD_OF_THE_RINGS"
console.log(toUpperSnakeCase("the quick brown fox"));   // "THE_QUICK_BROWN_FOX"
console.log(toUpperSnakeCase("code your future"));      // "CODE_YOUR_FUTURE"
